We've seen a very few men like Mandela in the last century. As pain is the most profound experience of human life, (not joy or love) it has formed Mandela as a man of rare qualities, of incredible strength, of balance. Having gone through unspeakable level of cruelty and injustice, Mandela has not become bitter and hateful and that is his hallmark. He surely has brought an unconventional meaning of freedom to his society by being freed from hatred and resentment.
Freedom is true when it is self-driven and when it is driven by others it is a form of slavery.
